Nothing ever happens in Roswell, New Mexico. Dorothy should know. She's lived her whole life on a rural ranch nearby, surrounded by the difficult memories from her family's struggles to make ends meet during the Great Depression years ago. At least her older brother Dwight is home safe from the war. Unfortunately, he's no better to talk to than her ancient pet sheep, Geraldine.

Thankfully Dorothy has her experiments, like launching rockets off the top of her windmill. But one stormy night, she sends a gigantic weather balloon into the stratosphere--and an incredible blast lights up the sky. Suddenly, all the newspapers feature a flying saucer crash in their headlines and the sleepy town of Roswell is alight with gossip and speculation. But what if the so-called extraterrestrial vessel is actually Dorothy's weather balloon?

When FBI agents start asking questions, she begins to suspect there's something out there, something dangerous. Either the government is after her for causing a national scandal...or aliens are real!
